Maybe if you're young (20s, early 30s)?

I recognize 8/10 as well, but like you, can't name actual songs from most.

Same would have been true if I was tested in the mid-90s (HS and college). Mariah Carey, Celine Dion, Backstreet Boys - I know the names, but can't think of the names of songs. I'd test better on alt/grunge rock of the era - STP, Nirvana, REM, etc.

And I don't think I'm particularly lonely - I happily married, have a few office friends, and see normal friends regularly. I'm not as social as I was in my 20s, but I assume that's normal.
